Look at your wrist, see the blueish veins? The blood flowing through them contains hemoglobin, a protein that has four iron atoms incorporated into its structure. Iron is only naturally produced in one place, it can only be forged in the core of dying stars.

Every time you look at your veins, remember that you are built from, and kept alive by, pieces of stardust.
